Review on 💧 Enhance Water Quality with Watts Premier WP531105 Annual Filter: A Comprehensive Solution by Sam Simone

First change red, yellow and blue once, and after 6-8 months change yellow and red. The most expensive part of our tap water is terrible, about 425, this filter makes 13 and lasts much longer than my old reverse osmosis filter which required unscrewing those canisters with a special wrench. Replacing cartridges is so easy, just press the button and the old ones pop out instantly! Slide the new one into place and you're done. After swapping them out I like to empty the storage tank and drain some water to make sure they flush inside. Good price for a year's supply (reverse osmosis element is separate and not included but does not need to be changed too often)
